Description

Technical Field

[0001] The present invention relates to a clamp for cleaning objects attached to a cable. Background Art

[0002] After the underwater data acquisition cables on offshore oil vessels are immersed in the sea for a period of time, a large number of marine organisms will attach to the cables. These marine organisms attached to the cables will increase the background noise of the collected data, double the tension on the cables, and reduce the ship speed. If the cables are regularly retracted to clean the marine organisms, the operating efficiency of the offshore oil vessel will be reduced.

[0003] The current common practice is to use hemp rope to wrap the cable, and then use a work boat to drag the hemp rope to clean the marine life on the cable. Although this method can remove some marine life attached to the cable, it also has the disadvantages of low operating efficiency, poor cleaning effect and high manpower consumption.

[0004] For example, the most widely used conventional three-dimensional operation cable configuration of the Offshore Oil 721 ship is 12 cables, each cable is 6,000 meters, and the total length of the towing cable is 72,000 meters. According to years of operation experience and data statistics, when using hemp rope to remove marine organisms attached to the cable, because the hemp rope is wound around the cable counterclockwise for removal, the winding strength of the hemp rope is controlled by manpower, so the removal effect is not good. Some marine organisms are still attached to the cable, and one person needs to use hand-held tools to manually assist in removal. Therefore, it takes 3 hours to clean a 6,000-meter cable. According to the calculation of cleaning marine organisms four times a month, the working boat operation time for cleaning marine organisms in a month is 3*12*4=144 hours. The fuel consumption of the working boat for removing marine organisms per hour is about 45 liters / hour, and the fuel consumption for removing marine organisms in a month is 45*144=6545 liters. In addition, during the operation, because the hemp rope is easy to wear and easy to break under the erosion of seawater, 15 meters of hemp rope is consumed every 6 hours of operation, and 144 / 6*15=360 meters of hemp rope is consumed per month. Summary of the invention

[0005] The present application provides a clamp for cleaning attachments on a cable, the clamp comprising:

[0006] A support pipe is constructed as a straight pipe;

[0007] A sliding rod, which passes through the support tube and can slide along the support tube, comprises a top end and a bottom end opposite to the top end;

[0008] A fixing frame, arranged at the end of the sliding rod;

[0009] A first movable frame, arranged on one side of the fixed frame and having one end hinged to the fixed frame;

[0010] A second movable frame, disposed on the other side of the fixed frame and having one end hinged to the fixed frame;

[0011] A first connecting rod, whose opposite ends are respectively hinged to the first movable frame and the supporting tube;

[0012] A second connecting rod, whose opposite ends are respectively hinged to the second movable frame and the supporting tube;

[0013] A first scraper, arranged on a side of the fixing frame away from the sliding rod;

[0014] A second scraper is arranged on a side of the first movable frame close to the second movable frame;

[0015] a third scraper, arranged on a side of the second movable frame close to the first movable frame;

[0016] Among them, the sliding of the sliding rod in the direction indicated by the end can drive the first movable frame and the second movable frame to open, and the sliding of the sliding rod in the direction indicated by the top end can drive the first movable frame and the second movable frame to move closer to each other so that the first scraper, the second scraper and the third scraper enclose a channel for the cable to pass through.

[0017] Compared with the existing method of using hemp rope to clean marine organisms attached to cables, the clamp in the present application has high cleaning efficiency, good cleaning effect and is simple and easy to use.

[0018] Other features and advantages of the present application will be described in the following description, and partly become apparent from the description, or be understood by implementing the present application.

[0043] When the clamp is used, the slide bar 2 is slid relative to the support tube 1 in the direction indicated by the end of the slide bar 2. The slide bar 2 drives the fixed frame 3 to slide in the direction away from the support tube 1. The end of the first movable frame 4 hinged to the fixed frame 3 follows the fixed frame 3 to move away from the support tube 1, and the first connecting rod 6 constrains the first movable frame 4 so that the first movable frame 4 can only rotate around the fifth hinge shaft 441, which makes the end of the first movable frame 4 away from the fixed frame 3 move in the direction away from the second movable frame 5; at the same time, the end of the second movable frame 5 hinged to the fixed frame 3 follows the fixed frame 3 to move away from the support tube 1, and the second connecting rod 7 constrains the second movable frame 5 so that the second movable frame 5 can only rotate around the sixth hinge shaft, which makes the end of the second movable frame 5 away from the fixed frame 3 move in the direction away from the first movable frame 4. Figure 4 As shown, the first movable frame 4 and the second movable frame 5 are separated from each other at one end away from the fixed frame 3, and the first movable frame 4 and the second movable frame 5 are opened. At this time, the cable can be put into the first movable frame 4 and the second movable frame 5 from the opening where the first movable frame 4 and the second movable frame 5 are opened, and it abuts against the first groove on the first scraper 33, and then the slide bar 2 slides relative to the support tube 1 in the direction indicated by the top end 21 of the slide bar 2. When the slide bar 2 slides relative to the support tube 1 in the direction indicated by the top end 21 of the slide bar 2 to the extreme position, the end of the first movable frame 4 away from the fixed frame 3 and the end of the second movable frame 5 away from the fixed frame 3 are close to each other, that is, the end of the second strip plate 41 away from the first sleeve 45 and the end of the third strip plate 51 away from the second sleeve 55 are close to each other. The bottom edge of the first notch 331 on the first scraper 33, the bottom edge of the second notch 421 on the second scraper 42, and the bottom edge of the third notch 521 on the third scraper 52 enclose a channel, the diameter of which is equal to or slightly larger than the diameter of the cable, and can allow the cable to pass through. At this time, the projections of the first strip plate 32, the second strip plate 41, and the third strip plate 51 in the direction perpendicular to the plate surface of the first scraper 33 form a ring, the projections of the first scraper 33, the second scraper 42, and the third scraper 52 in the direction perpendicular to the plate surface of the first scraper 33 form a ring, and the projections of the bottom edges of the first notch 331, the second notch 421, and the third notch 521 in the direction perpendicular to the plate surface of the first scraper 33 can form a perfect circle, which is the projection of the above-mentioned channel. When the cable is in the channel, the clamp is moved along the extension direction of the cable, and the attachments on the outer peripheral surface of the cable can be scraped off by the first scraper 33, the second scraper 42 or the third scraper 52. The attachments may be marine organisms attached to the cable.

[0044] In an exemplary embodiment, the first scraper 33, the second scraper 42 and the third scraper 52 are all made of resin material. The first scraper 33, the second scraper 42 and the third scraper 52 made of resin material will not scratch the insulation layer of the outer layer of the cable when sliding along the cable. At the same time, the friction between the first scraper 33, the second scraper 42 and the third scraper 52 and the cable is small, which is more labor-saving. The first scraper 33, the second scraper 42 and the third scraper 52 made of resin material have high hardness and are not easy to deform.

[0045] In an exemplary embodiment, the clamp further comprises a driving mechanism 8. The driving mechanism 8 comprises a pressing rod 81, a first handle 83 and a third connecting rod 82.

[0046] The pressure rod 81 is in the shape of a straight bar. The pressure rod 81 includes a first end 811 and a second end 812 opposite to the first end 811. The end of the first end 811 is hinged to the top end 21 of the slide bar 2. The first handle 83 may be a rectangular ring. The first handle 83 is arranged at the second end 812 of the pressure rod 81 and is located on the side of the pressure rod 81 away from the support tube 1. The plane where the first handle 83 is located is perpendicular to the extension direction of the pressure rod 81. The third connecting rod 82 is a straight rod. The cross section of the third connecting rod 82 may be rectangular. One end of the third connecting rod 82 is hinged to the end of the support tube 1 away from the fixing frame 3. The other end of the third connecting rod 82 is hinged to the pressure rod 81, and the connection of the third connecting rod 82 on the pressure rod 81 is between the end of the first end 811 and the end of the second end 812. The distance between the connection of the third connecting rod 82 on the pressure rod 81 and the connection of the top end 21 of the slide bar 2 on the pressure rod 81 is less than the length of the third connecting rod 82.

[0047] Pulling or pressing down the first handle 83 can make the pressure rod 81 swing relative to the slide bar 2. When the free end of the pressure rod 81 swings away from the support tube 1, the pressure rod 81 can drive the slide bar 2 to slide in the direction pointed by the end of the slide bar 2, thereby driving the first movable frame 4 and the second movable frame 5 to open. When the free end of the pressure rod 81 swings toward the support tube 1, the pressure rod 81 can drive the slide bar 2 to slide in the direction pointed by the top end 21 of the slide bar 2, thereby driving the first movable frame 4 and the second movable frame 5 to move closer to each other.

[0048] In an illustrative embodiment, the clamp further includes a second handle 9. The second handle 9 may be a rectangular ring. The second handle 9 is connected to the outer peripheral wall of the support tube 1 and is located in the middle of the support tube 1. The plane where the second handle 9 is located is perpendicular to the extension direction of the support tube 1.

[0049] When using the clamp, one hand can hold the first handle 83 and the other hand can hold the second handle 9, which makes the operation more convenient.

[0050] In an exemplary embodiment, two through holes may be respectively provided at both ends of the crossbeam 31. A rope may be passed through one of the through holes and fastened to the crossbeam 31, and the rope may be pulled along the extension direction of the cable to drive the clamp to move along the cable, which is more labor-saving.

[0051] In a specific embodiment, after the clamp is put into actual operation, the efficiency of cleaning work is significantly improved compared with the traditional hemp rope. Previously, it took 3 hours to clean 6,000 meters of cable using hemp rope, but with this clamp, the cleaning work of 6,000 meters of cable can be completed in 2 hours. Since the clamp is used to thoroughly remove marine life, after using the clamp for cleaning, the original four times a month to remove marine life is reduced to three times. For the Marine Oil 721 ship towing 12 collection cables, each cable is 6,000 meters, the working time of the workboat to remove marine life will be reduced from the original 3*12*4=144 hours to 2*12*3=72 hours per month, shortening the working time and significantly reducing the fuel consumption of the workboat. The theoretical value of fuel consumption per hour for a workboat to remove marine life is about 45 liters / hour. After actual calculation, the fuel consumption has dropped from 6545 liters per month to 3242 liters. Calculated at 5525 yuan / cubic meter of diesel, the average monthly fuel cost savings is 18,200 yuan. If the marine life removal operation is carried out for 6 months a year, the annual fuel cost savings can be 1.82*6=109,200 yuan.
